This section details on the original issue you should resolve

<issue_title>RdlViewer methods(Hide/ShowRunButton) not working!</issue_title>
<issue_description>As we know, the methods(ShowRunButton and HideRunButton) control the visibility of 'Run Report' Button.
But any method is not working.

For fixing the problem, add some codes in the source 'RdlViewer.cs'.

(Line 2145)
public void HideRunButton()
{
_ShowParameters = false; //<- Add this Line
_RunButton.Visible = false;
}

(Line 2150)
public void ShowRunButton()
{
_ShowParameters = true; //<- Add this Line
_RunButton.Visible = true;
}

I hope that this issue is resolved ASAP!</issue_description>
